Great! Exactly what I needed; bought some film to try out this great lens that I have for my old Canon A-1. I don't have a light meter, and I don't trust the built-in one, so I'll be using my digital EOS for light setup and metering. The widest aperture on the lens on the EOS is 5.6, the widest on the old lens (a 135 mm fixed length) is 2.5, and, being so used to all the automatic settings on the EOS, I'm slightly out of practice when it comes to exposure converting. This is gonna save me a lot of pain, thanks!

Not for me Well I have tried it but it isn't as good as the others make out. I have contacted the App creator but got no reply. I just want to find out what shutter speed to use to get a correct exposure when using ND filters. Sounds easy of course but. I don't want to be doing test shots of 6mins long (as an example) and wasting my life in doing so. I want to then be able to crank up the iso to 1000 and above to get an exposure. I will then put it back to iso 200 and go for the long,and correct exposure. It calculates the exposure wrong if you start to change the iso. Good effort though from the creator but not really good enough

Great app. Very flexible. A must for ND110 use Just wish I'd found this earlier - simple and effective once you understand what it's doing and really useful when using strong ND filters. Those reviewers marking it down because it stops at 9 stops don't understand how it works - look at the equivalent exposure and you'll understand. By default I think it uses a current exposure of 30secs - when you go to +9 stops adjustment this becomes 256 minutes of equivalent exposure! If you went to 10 stops this would be 512 minutes (are you really going to stand there with the camera in Bulb mode for 8 hours?). Once the current exposure is set to something more reasonable (e.g. in most conditions you'd likely be at 1/30th or above) you can then dial in 10 or more stops adjustment (I.e. the app is placing an upper limit on the equivalent exposure of 256 minutes).

Awesome application This is a great exposure calculator. Simple and straight forward to use. Excellent!

Works well - needs a timer This app works well in calculating the exposure but would benefit from having timer functionality. Also you need to look at the UI for tablets. Address those points and you'd get 5 stars from me

Software no longer supported EDIT: The dev responded to a recent inquiry and stated this app will no longer be developed. If you have issues, you may not get a resolution. This was a very effective app for me when it worked. -- None of the radio buttons work on my 2014 Moto X. Tested across two .models on 4.4.4. Any help from the Dev would be appreciated. 3-starring because the app worked well in the past.

Not calculating correctly!! The interface is great and exactly what i'm looking for, but it does not calculate correctly. If you decrease ISO, it will also increase the Fstop# (decrease aperture size). This is the opposite of what should happen. If you decrease ISO, your aperture should get larger, not smaller (should lower Fstop#).

Perfect for on the fly exposure Very simple app to perform quick exposure cals when I use my big stopper nd10 filter. No more wasted time trying to calculate the exposure in my head. Thanks for a great app!

Useful for ND filters Exactly the app I've always wanted to write. Exposure in, equivalent exposure out + configured stops. I don't see any issues with changing iso like others describe. The app does round unnecessarily when you are already well into bulb mode territory, but the difference in actual exposure is mostly negligible. Would like to see enhancements as presets for filters

Great! with 1/3 stop increments. Finally an app that allows me to switch the aperture and iso by 1/3 stop. Calculating with "exact" apertures (2,8; 4...) is pretty easy once you're used to, but when you start with 1.8 or 3.5, you do not always remember the multiplying factors. This app contains the one and only thing I needed, thanks! It is straightforward, you don't need to explore three menus to get to what you want.

Works On The Fly! When you have your settings perfect for a single or couple portrait, now there is a huge group and you need to reset the ISO, F-stop, & shutter speed...plug just either of the three options to get the correct exposure without guessing or testing. Exp: F4.5 to F8.0 [new shutter & ISO to match]

A few more options possibly A really nice useful app, but there is one thing i'd like to see. 1. The ability to use the ND value of a filter i.e. ND4, ND8, ND400 rather than having to work out the stops. There is also a bug, hitting Calculate Aperture in settings closes the app, at least on my Galaxy S2 any way.

Very nice Great app for calculating exposures. I use this when star-trailing in a single shot. Usually make the shot with very high iso and short exposure time and then calculate the new values using like 15'. Works like a charm. Congratz !

Excellant Exactly what I was looking for. Just wish it would go above 9 stops diff. Why? I have a 9 plus 4 so I compose the shot with no filters and take a reading and then I want to know what the speed would be if I added the 2 filters stacked together. Currently I have to work it out manually or add the 4 then take a reading then use the calc then add the 9. Would like the flexibility to specify 13 in the calc.

"Smart Hide Calculator" is a fully functional calculator app but with a little twist. Once you enter the password(u get to set it on first start of app and can also be changed in future) and press the '=' button then boom you are presented to an interface where you can hide, unhide pictures, videos, documents or files with any file extension placed in a folder on sdcard, and if your device have root you can also hide (freeze) and unhide (un-freeze) apps.

Features:1.) Everyone will think it as a simple calculator2.) Hide and Unhide pictures, videos,documents or any other media type3.) Hide and Unhide apps **ROOT REQUIRED4). Don't show itself in recent apps5). In case user forgets the password he can recover it by going into password recovery mode(by pressing 123456789+987654321 in calculator) and providing the secondary password6). View hidden files without unhiding them again

More and more features and improvements will be made available soon. Suggestions are always welcome.

Note: 1. The secret screen's UI(the one with hide and un-hide buttons) may look a little weird on small screen sizes2. Refresh gallery button will not work in android kitkat 4.4 (and it is not possible fix this). Don't worry its not even needed and will most probably be removed in future release.

Calculator extends the 4 function calculator. It's simple and uncluttered, but gives you access to advanced functions with a swipe. Graphing, matrices, base conversion, and more are at your finger tips, and only when you need them.

Calculator also has a widget, a floating calculator, and 7 (and counting) alternative themes. It also runs on Google Glass.

History:Calculator was started in June 2012, by Will (myself) and Sean, as developer and designer respectfully. Over 4 months, we added basic support for matrices, graphing, and history, and in October 2012, Calculator became officially included within CyanogenMod (and most custom ROMs soon thereafter). In January 2013, Nick joined the endeavor, redesigning the graph page, hex page, and has, more recently, created all of the available themes. In September 2013, Rudy joined for a short time and greatly improved the matrix logic, adding support for functions, order of operations, and more. And, of course, the vast language support has all been thanks to users. The calculator has been, since its start, open source, and is always looking for more helping hands.

Advice:Because the app is intended as a full replacement, it's recommended that you disable your default calculator. Go into Settings, Apps, and you will be able to disable it where you would normally find Uninstall (Requires Android 4.1+).
